Thanks for information about fournales,but I installed many years ago Fournales on my bike(in the eighties :-)) kawasaki ST1100), but they're tricky to use ,
the system need always special material like a special pump etc.... ok..
Well I suppose you ask me if I'm australian, in this case as my name Hugues from Portugal(the european country) do you know arnott air suspension......?
ok :)
